` claims. (01.,272-48) `My invention vvrelates generally to vexercising: apparatus, particularly of the type generally reierred to as punching bags and theprincipal object of my invention is, to provide a punching 5 bag of simple, strong and'sturdy construction, that will enable the user to derive exercising beneiits that are practically .equal to boxing, without the attendant danger of injury.

Further objects of my invention are, to provide a punching bag of the character referred to that is mounted on the upper end of a resilient standard and to provide simple and eiilcient means whereby the lower portion of the standard may be adjustably positioned in theA oor, ground,

or pavement,y in order that the bag mounted on the upper end of the standard may be located at different heights so as to be conveniently struck by persons of dierent'heights, further, to prol vide a highly resilient neck .connection between the upper end of the resilient standard and the ball that is struck by the users ofthe appliance, which resilient neck permits the ball to yield readily when struck and to instantly return to its normal position and further, to provide a punching bag wherein the' so-called bag comprises an inatable ball of rubber provided at its lower end with `a depending extension of solid rubber that is connected to the upper end of the resilient member Vthat is connected to and` extends upwardly from the resilient standard.

With the foregoing and other objects in View,

my invention consists in certain novelfeatures of construction and arrangement of parts that will be hereinafter more fully described and claimed and illustrated vin the accompanying drawing in which:

Fig. 1 is a side elevationalview of a punching I bag constructed in accordance with my invention. Fig. 2 is an enlarged vertical section taken on 40 the line 2-2 of Fig. 1. I

Fig. 3 is an enlarged horizontal section taken on the line v3 7 of Fig. 2. i Y Fig. 4 is a vertical section taken through the member that connects the lower end of the ball or bag to the resilient extension on the upperend of the standard. n

Fig. 5 is an enlarged elevational view of the upper end of the resilient standard.

Fig. 6 is an enlarged detail section showing the adjustable mounting for the lower end of the resilient standard.

Fig. 7 is a vertical section taken through the lower portion of the iiexible connection used between the standard and the ball or bag.

v Fig 8 is a detail Vertical section of a further `and which may be located in the floor, ground,

or cement. y

In order that the bagy may be'adjusted into diierent vertical positions so as tovbe conveni- 115 ently used by persons of different heights, a num ber ofV transverse apertures i3 are formed `through the lower portion of the standard and which apertures. are adapted to receive a pinorl lkey s4,which1a.tter rests on top of the socket la. 20 l' Screw seated in the thread l l and projecting upwardly from the standard. i6, is the lower portion of va coiledk spring I5, the convolutions of which are spaced slightly apart. Three or four of the convolutions at theupper 4end of the v25 spring are screw seated in the threaded portion of a connecting plug member I6, which member includes an integral upwardly projectingV por' tion Il of slightly reduced diameter and which `is externally threaded as designated by I8. y30y -Disposedvwithn the spring l5 between the` upper end ofrstandard il! and the lower end-oi connector plug I6, is a tube. i9 composed of practically pure rubber and having a fairly thick i 1 lWall and which co--operates with the coil spring ,35

in producing a substantial degree ofvr resiliency lbetween the standard I@ and the inflated ball or jbag that is mounted on the upper end of the In order to control the degree of resiliency of ,40

the connection between the standard and bag,

tubes having walls that vary in thickness may be utilized and, in some instances a tube having an external diameter slightly greater than the internal diameter of the convolutions of the 45 spring may be used. In order to insert a tube of this character within the spring, it is necessary to utilize clamps or the like andr unwind the spring to a suicient degree` to permit the tube to be inserted therein and, when the `ends 50,

of the spring are releasedand the convolutions thereof contract slightly they will grip the inserted tube and produce a strong and substantial-connection'having the desired degree of ref siliency. 55

In some instances, it may be found desirable to wrap a narrow strip Zllof resilient material, such as practically pure rubber, between the convolutions of the spring I5 and to retain this resilient strip in position, it may be cementedr or vulcanized directly to the rubber tube I9 (see Fig. 7).

A further modified construction is illustrated in Fig. 8 wherein a tube I9a of practically pure rubber encloses the coil spring I5..

The bag or ball utilized in my improved eX- ercising appliance comprises a hollow substantially spherical body 2l of rubber which may, il. desired, be reinforced with fabric or other suitable material.

Located in the top of the ball is a conventional valve 22, which when open permits the ballto be inilated after which the valve is closed to maintain said ball in such inflated condition.

The lower half of the wall of the ball or bag gradually increases in thickness and the lower portion of said wall unites with an integralA depending member 23 that gradually tapers toward its lower end.

Formed in this depending tapered member 23', is an internally threaded recess 24 which receives the externally threaded extension il of plug IG.

By providing a detachable connection between the ball or bag and member I6 and a detachable connection between the lower end of spring I5 and standard Ill, the parts of the bag may be readily disassembled so as to occupy comparatively little space when packed for storage or transportation.

To set the bag up for use, the lower end of standard IEI is inserted in tubular socket I2 and said standard is adjusted verticallyto position the ball so as to be conveniently punched by the user and, the standard is maintained in such adjusted position by positioning the key or pin I4 in one of the apertures I3, with said key resting on top of the socket. It is to be understood that when the device is in use, the ball or bag 2| is inflated and which operation is accomplished through the valve 22 and, that the latter is closed after the ball has been inilated to the desired degree.

The person using the exerciser strikes the ball with the clenched fists and due to the resiliency of the standard I and particularly the resiliency of the spring and rubber connection between the standard and the: ball, the latter will readily yield as a result of the impact of the lst against the ball so that the latter will swing away from the iist and immediately return to its normal position as the resilient standard and resilient connection between the stndard and ball return to their normal positions.

To disassemble the apparatus for storage or transit, it is only necessary to unscrew the lower portion of the spring I from the upper end o f the standard and to unscrew the upper portion I'I of the plug connection from the tapered body 23 that depends from the bottom of the ball or bag. l

Thus it will be seen that I have provided a punching bag that is relatively simple in construction, inexpensive of manufacture, and very effective in performing the functions for which 'it is intended.

lIt will be understood that minor changes in the size, form and construction of the various parts of my improved punching bag, may be made and substituted for those herein shown and described, without departing from the spirit of my invention, the scope of which is set forth in the appended claims.
